Abstract

The application provides an extraction structure, comprising: a Soxhlet extraction mechanism having an extraction tube for holding a to-be-extracted sample; the ultrasonic transduction mechanism is located on the outer side wall of the extraction pipe, and at least part of the first end of the ultrasonic transduction mechanism makes contact with the outer side wall of the extraction pipe; the ultrasonic transduction mechanism is used for controllably emitting ultrasonic oscillation into the extraction pipe. The invention further provides a residual pesticide extraction device and residual pesticide detection equipment.

Description

technical field [0001] The application belongs to the technical field of substance separation and extraction, and in particular relates to an extraction structure, a residual pesticide extraction device and a residual pesticide detection device. [0002] technical background [0003] Pesticide residues refer to the general term for pesticide precursors, harmful derivatives, metabolites, degradation products and impurities that remain in the environment, organisms (such as agricultural products or livestock) and food after pesticides are used. Usually, the excessive amount of pesticide residues in agricultural and animal husbandry products such as vegetables, fruits or livestock is mainly due to some organophosphorus pesticides and amino acid formate pesticides that are prohibited from being used in the production of agricultural and animal husbandry products. The residues of these pesticides will have a greater impact on humans and animals, and even cause harm such as acute p...
